I had my interview at Dallas DO and my experience is in line with other people in this forum. My interview was at 10 and went a bit early. They only allow people exactly 30 minutes prior to the interview time. They are very strict about this. Also no cell phones allowed inside the building. Once inside I sat in the area marked 'Naturalization interviews'. Do not attempt to sit in any other waiting area as you will not hear when your name is called. With all the noise you need to be real attentive.
I was led into a room and before I was asked to sit with my hand raised I was told that I was under oath to tell the truth. I was asked only for my current passport and greencard. No Social Security card or driver licence. It is better to take it though. The officer was very professional and courteous. I had some changes like trips outside, change of employment etc. from the time I had applied and it was marked in red ink and numbered accordingly. I was asked if any of trips lasted over 6 months and my passport was checked (though not in detail - I had a number of trips and stamps). All the questions in the application were reverified in detail. I had a few traffic tickets and when I asked if they are expected to be reported, the answer was Yes we need to report it as they are citations from a law enforcement officer but this will not have any bearing on the application. I was asked if I had filed all taxes and owe any back taxes, whether I will bear arms for the country, etc. I was then asked 6 questions straight out of the 100 standard questions on the website and I got all of the 6 right. I was asked to read and right a simple sentence and with that I was done. She gave me the form N-652 stating that I have passed the interview and is being recommended for approval. I was asked to write my full name in cursive manner on the white side of the photo I had sent with the application. I asked if they have got all the clearences and the answer was Yes. I was told that I will get an invitation for 'one of the several oath ceremonies planed in Dec.' Now it is going to be a wait to get the Oath letter in the mail. What I dont understand is that some people have gotten the oath letter right after the interview and some have been told to expect it in the mail.
Well, hopefully people waiting for interviews will get something out of this experinece and in turn share theirs in this forum. That is the purpose of this wonderful forum. I had kept all my papers organized (tax copies, selective services letter, bank statements, pay stubs, utility bills, past employment letters, etc.) but were never asked for all that. Good luck to everybody and hopefully I will get my oath letter within this month.
